Abbreviated as OIS, optical image stabilization is the apparatus, contained within a digital camera or other digital recording device, that compensates in real-time for shaking and vibrating while recording. Because OIS is a real-time compensation there is no alterations or image degradation to the image.
- optical resolution
The physical resolution at which a device can capture an image. The term is used most frequently in reference to optical scanners and digital cameras. In contrast, the interpolated resolution indicates the resolution that the device can yield through interpolation — the process of generating intermediate values based on known values. For example, most scanners […]
- Optical Scanner
A device that can read text or illustrations printed on paper and translate the information into a form the computer can use. A scanner works by digitizing an image — dividing it into a grid of boxes and representing each box with either a zero or a one, depending on whether the box is filled […]
- optical viewfinder
On a digital camera optical viewfinder is the eyepiece that you look through to frame and focus your subject before taking the picture. Because the optical viewfinder and your camera lens are not positioned the same way (e.g. the viewfinder is located above the camera lens), you may notice your final image is not an […]
- optical zoom
On a digital camera, optical zoom is a true zoom feature. It allows you to zoom in (or out) on the subject in the LCD or viewfinder. This will enable you to get a closer view of the subject before taking your picture. Optical zoom changes the magnification of images with the actual optical glass […]
(1) In programming, to fine-tune a program so that it runs more quickly or takes up less space. (2) When applied to disks, the term means the same as defragment. See under fragmentation. (3) To configure a device or application so that it performs better.
